Specification of Letters Patent.

Patented Feb. 20, 1912.

Application filed August 7, 1911 Serial No. 642,774.

To all whom it may concern:

Be it known that we, ()LEY L. LEDINGTON and Jnmus SANDELL, citizens of the United States, residing at. Marquette, in the county of McPherson and State of Kansas, have invented certain new and useful Improves ments in Culvert-Molds, of which the following is a specification.

Ourinv-ention relates to imprtvements in culvert molds.

The object of our invention is to provide aculvert mold which is simple in construction, efiicientin operation and which may be readily knocked down and removed from the operative )osition after the material forming the culvert has become set. a

The novel features of our invention are hereinafter fully described and claimed.

In the accompanying drawings, which illustratethe preferred form of our invention, Figure 1 is a longitudinal vertical seetiona-l view of the mold set up in operative position, on the line c([ of Fig. 2 Fig. 2 is an end view of the same. Fig. 3 is an enlarged cross section on the line ef of Fig. 1, thesupplemental side members being removed. Fig. 4 is a perspective view of the Fig. 5 is a longitudinal sectional view on the line a--7) of Fig. 2.

Similar reference characters similar part-s.

1 and 2 designate respectively the two main side members of the mold. Secured to the inner side of the member 2 are vertical cleats which are adapted to have their upper ends" support one set of ends of arches 4 the other set of ends of which are designate adapted to be supported. upon the upper ends, preferably rounded, of a plurality of members 5 pivoted to the inner side of the main side member 1 by pins 15. A longitudinally movable member comprising preterins 8 to the members 5 above the pins (3. ne end of the bar 7 is pivoted to a lev-er'tl by a pin 10, said lever being pivoted by a pin 11 to the side member 1. A bar 12 parallel with the bar 7 is ivoted by pins 13 to the members '1 5 below t 1e pins 6. The bar. 12 is pivoted to the lever 9 by the lever 9 being disposed between'the pins a pin 14,-'t-he' pin supporting ltland 14.

' To releasably lock the lever in the position shown in solid lines in Fig. 1 any suitable means may be provided. In the drawing'we have shown the'lever 9 provided.

with a bolt 15 which is adapted to engage a notch. provided in the upper side of an arcuate plate 1.6, which in turn is secured to the side member 1. The bolt 15 is actuated by a. rod 17 connected to a bell cran'k lever 18 pivoted to the lever 9. 1

One or more latch bars 1.9 are pivoted to the member 2 and are adapted to rele-asably engage eyes 20 respectively which are secured in the side member 1., for releasably bracing the members 1 and 2 in the operative position.

Secured to the bar 7 are one or more plates 21 which extend upwardly from the bar 7 and are disposed respectively under the latch bars 19 in such positions that when the bar 7 is moved in the proper direction to release the arches 4 from the pivoted members 5, the bars 19 will be disengaged from the eyes 20.

Mounted oh the arches 4 are longitudinal roof members 22, one of which, preferably the middle one, is detachably secured to the arches 1 by hooks 23 which engage eyes 24 secured to the arches.

Supporting the main side members 1 and 2 respectively are supplemental side memhers 25 and 2G. Secured to the inner side member 26 are vertical cleatsv 27 which extend above the lower edge of the side member 2 to prevent the inward movement of the said member 2. A horizontal bar 28 is secured to the cleats 3 in a position such that the upper ends of thecleats 27 will have their inner sides engaged by the bar. 28, thus holding the supplemental member 26 in 0per'a-tive position. Secured to the inner side of the supplemental member 25 are cleats '29 which extend above the lower edge of the side member 1, and are adapted. to have their inner sides engaged by the bar 12, when the bar 12 is in the position shown in solid lines in Fig. .1;

Cross bars 30 are adapted to be inserted between the supplemental side rnenibers 25 and 26, as shown in Figs. 1 and 5, for holdthe side members 25 and 26 spaced apart 1n the operative positions. As shown Fig. 3, when the supplemental side members 25 and 26 are not used, the cross bars 30 may be disposed between the main side members- 1 and '2. i

In the operation of our invention, the supplemental side members 25 and 26 being employed, the parts having been assembled as described with the pivoted members 5' supporting the arches/L, by swinging the lever 9 to the position shown in dotted lines in Fig. 1, the pivoted members 5 are swung by the bars 7 and 12 to the positions shown in dotted lines in Fig. 1. The ends of the arches 4 which have been supported by the members 5 will now be unsupported, and the plates 21 will have released the latch bars 19. At the satne time the cleats 29 will be released from the bar 12. The mold may now be collapsed and the parts Withdrawn from the culvert which has been built upon the mold. The arches 4 being secured to the middle roof member 22 can all be witl'idrawn by withdrawing said roof member.

If desired the supplemental side members 25 and 2G may be dispensed-with, in which case, as stated above, the cross bars 30 are mounted between the main side members 1 and 2. In such case the mode of operation is th same as has been described.

li e do not limit our invention to the structure shown and described, as modifications, within the scope of the appended claims. may be made without departing from the spiritof our invention.

Having thus described our inventiomwhat we claim and desire to secure by Letters Patent, is

l. in a culvert mold, two side members, releasable bracing means connecting the side membcrs,a plurality of arches, lneanson one side member for supporting one set of ends of the arches, movable means for supporting the other set of ends of the arches, a lever, and means actuated by the lever for releasing the bracing means and simultaneously moving the mo able supporting means from positions supporting the arches.

2. In a culvert mold, two side members, releasable means for connecting and; bracing the side numbers, a plurality of arches, means on one side member for supporting one set of ends of the arches, movable ln'embcrs supported bythe othcr side member for supporting the other set of ends of the art-hrs. a longitudinally movable mcmbcrfor simultaneously moving the movable men bers from positions in which the] are adapted to support-tho arches, means carried by.

the longitlulinally movable member for releasing the bracing means when the longi lndlnally movable member is moved to \VlllL- draw the movable members from positions supporting the arches, and means for longisubscribing witnesses.

tndinally moving the longitudinally movable member.

3. In a culvert mold, two main side mem here, a plurality of arches, two supplemem tal side members adapted to respectively support the,main side members, upwardly; extending cleats on the inner sides of the supplemental side members for enga ing and holding the main side membersom inward movement, means on one main side member for supporting one set of ends of the arches, movable means on the other main side member for supporting the other set of ends of the arches, and a longitudinally movable member for engaging the in ner sides of the adjacent cleats and for moving said movable means from positions in which they are adapted to support the arches, the longitudinally movable member when moved to disengage the movable supporting means from the arches being disposed so to release the adjacent cleats.

d'flfi a cu,lvert-.mold, a-Jiiainnside-member; a supplemental side member for supporting the main side member, cleats on the inner side of the supplemental side member for engaging and holding the main side member from inward movement, members piv otally mounted on the main side member,

her, a supplemental side member for supporting the main side member, cleats on the supplemental side member for holding the main side member from inward movement, members pivoted to the main side member for supporting arches, a longitudinally movable member connecting said pivoted members and movable to and from a position in which it will enga e the inner sides of said cleats, and a lever For longitudinally moving said longitudinally movable mem ber.

In testimony whereof we have signed our names to this specification inpresence of two 'OLEY L. LEDINGTON. JULIUS SANDELL.
